3 0

The expression which shows how the distributive property of the can be used to multiply 8×29 as in the task content is; 8(20 + 9).

<h3>Which expression can be used to show how the distributive property can help multiply 8×29?</h3>

It follows from the task content that the given product to be multiplied is; 8×29.

Consequently, it follows from convention that the distributive property of multiplication allows that the multiplication in this case can be rewritten as follows;

8×29 = 8 (20 + 9)

Hence, we have; (8×20) + (8×9).

Linkin Corporation is considering purchasing a new delivery truck. The truck has many advantages over the company’s current truc

Romashka [77]

Answer:

Payback is 7.3 years

NPV $3,099

Step-by-step explanation:

The formula for payback period period=initial investment/annual cost savings

The initial investment is the amount of cash outflow that would be required to purchase the new delivery truck,which is $54,750,while on the other hand the annual cost savings is $7,500

cash payback period=$54,750/$7,500=7.3 years

Ordinarily,the expected payback is 1/2 of 8 years=4 years.

The net present is the present worth of the future cost savings as well as the scrap value of the truck in year 8,calculated by multiplying the cash flows with the discounted factors for relevant years as below:

Years cash flow DCF at 8% Present values

0 -$54,750 1 -$54,750

1-7 years $7500 5.2064 $39,048

8 $34,800 0.54027 $18,801

NPV $3,099

Note that the $34,800 =$7500+$27300

The year 1-7 factor is annuity factor for 8% 7 years

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 9% vinegar, and the second brand co

tester [92]

First brand = A, second brand = B.

A + B = 249ml
9% A + 14% B = 13% 249ml

B = 249ml - A
9% A + 14% (249ml - A) = 13% 249ml

9A + 14 (249ml - A) = 13 * 249ml
9A + 3486ml - 14A = 3237ml
5A = 249ml
A = 49,8ml
B = 249ml - A = 199,2ml

Answer: He should use 49,8ml of first brand and 199,2ml of second brand.

Also note: That's an approximation, because the volumes are not strictly additive. For example: mixing 50ml pure ethanol with 50ml water will give you about 95ml of mixture. To get an accurate answer, you'd have to measure the volume of the final mixture and then divide your total alcohol content by that.
